WILLIAM J. BRUNELL, OF DETROIT, IVIIOI-IIGAN.

SKATE SHARPENER.

' Application filed. October 26, 1921.-

To all whom it may concern Be it known that I, l VILLIAM J. BRUNELL, a citizen of the Detroit, in the county of lVayne and State otMichig-an, have invented certain new and useful Improvements in Skate Sharpeners, of which the following is a specification.

This inventionrelates toskate sharpeners'and more particularly to an improved skate file and file holder adapted to be used for grinding and grooving the edges of skates. g

The primary object of the invention is to provide a file which will be adapted to sharpen the skates in a manner known as hollow grinding and groovin Other objects of the invention will appear upon consideration of the following detail description and accompanying drawings, wherein 7 Figure l is a side elevation of the file, Fig. 2 is a cross-sectionon the line 2-2 of Fig. 1, c

-Fig. 3 is a side elevation of the file holder, Fig. 4 is a cross-section on the line 4+4 of Fig. 3, and

Fig. 5 is a cross-section showing the holder and file assembled for use.

Referring to the drawing by numerals, the file 1 is substantially square in cross section and is provided oneach face with filing surface 2. Thelo'ngitudinal edges at diametrically opposite points are rounded as indica ed at 3 while the opposite longitudinal edges are square as indicated at 4. This file may be of any desired length and is adapted to be mounted in a file holder 5 which consists of a tubular member 6, a longitudinal slot 7 extending throughout its entire length and nal flanges 8 extending from the marginal edges Oil the slot, these flanges Sbeing adapted to engage the opposite sides oi the skate blade when the device is in use. Outwardly turned ears 9 on the end of the flanges 8 are provided to form finger grips whereby the holder may be manipulated when'it is in use.

In rder that the file will be properly held in the holder,

United States, residing at.

comprising a file of any provided with longitudi I both the file and the Serial No. 510,638.

holder are provided with bolt openings to receive the removable bolts 10 which are e.

tended through the openings and fastened with nuts or other removable means.

When the file holder is in use, the file will be placed within the tube 6 andone oi" the edges 3 turned so that it will be in alinement with the slot 'Zwhereupon the flanges 8 will be engaged with opposite sides of the state blade and the longitudinal slot will be reciprocated in the usual manner. The rounded edges 3- will hollow grind the edge of the skateand if the user desires a groove to be provided in the edge of the skate he may-simply reverse the position oi the tile in the holder by removing and rearranging the bolt 10 so that the lower edges 4 will be in a position to grind the edge of the skate. In this manner a perfectly ground skate may be provided with either a hollow grind or a longitudinal groove.

Minor changes may be made in the de tails of construction without departing from the spirit of the invention or the scope of the claim hereunto appended.

hat is claimed is An implement oi the character described desired length substantially square in. cross-section, two of its opposite marginal edges being rounded, the other two longitudinal edges being square, a file holder comprising ceive the said file and provided with a longitudinal slot adapted to be alined with one of the longitudinal edges of the said file, the said tube being equipped with longitudinally extending flanges extending from the marginal edges of the said groove, means to removably hold the file within the tube wherehv any one off the file edges may be alined with the said longitudinal groove, each longitudinal flange being equipped with a finger grip whereby the said tube may be manually moved when it is in use.

in testimony whereof, I have aiiixed my signature in the presence of two witnesses.
